Abstract

1. Power chuck with several clamping jaws (2) radially movably guided in a chuck body (1), which jaws are operable by means of a setting member (3) movably guided in the chuck body (1), and with jaw locking devices, which in each case surround a positioning pin (4) engaging into a recess (2a) of the clamping jaw (2), which pin can be retracted out of the recess (2a) by means of a manually operable latch member (7) positively engaging it, where each latch member (7) is supported in the working area of the setting member (3) directly on a surface of the setting member (3), and is able, when the setting member (3) has been moved over to a disengaged position, to be pushed against the force of a return spring (5) into a groove (3b) in the setting member (3) or into a space vacated by the setting member (3), characterised in that the positioning pin (4) in the working area of the setting member (3) is positively forced by the latch member (7) into its latching position engaging into the recess (2a) of the clamping jaw (2), and in the disengaged position of the setting member (3) can be retracted manually from the recess (2a) by operation of the latch member (7).
